, This invention relates to machines for inserting fastenings and has for its object to provide improved mechanism for varying the operation of such a machine on the Work as i frequently rendered necessary or desirable b dissimiliarit in character of the y,

separate pieces of Work operated upon or of different parts of the same piece of Work.

The invention Wlll. be hereinafter de- S(31'll3(3Cl,,lJY Way of example, as applled to a machine for inserting loose nails of the type disclosed in the Patent toGoddu, 1,030,775, June 1.912. in order to adapt machines of such type for operationon pieces of shoe stock of different thicknesses or on stock which varies iuthicliness at the points Where nails are inserted, the racevvavs of the machines are formed with a plurality of slots adaptedto contain nails of different lengths, and means are provided for causing nails of rm-ilatively great length to be supplied to the fastening inserting mechanism for insertion into relatively thick stock and for causing nails of less length to be supplied to the his toning inserting" mechanism when relatively thin stock is being operated upon. The con-Q ditions WlllCll require change in the length of: the nails being inserted also frequently make necessary a change in the position of the gage liiy which the Work is guided in the open otion of such machines. For exampla tvhen nailing around the edge of a shoe, the thiclc ness of the stock through which the nails are,

driven is frequently greater at theiforepart tlan 1n the shank, by reason, for instance. of

the interposition of a slip sole between the mitsole and insole at the forepart. Consequently, it is advisable to insert a longer nail in the forepart than in the shank. The edge of the outsole also frequently projects farther beyond the edge of the insole at the forepart than in the shank, for which reason the gage should preferably be moved away from the plane of operation of the fastening inserting mechanism upon the initiation of the insertion of long nails to cause the row of nails to be spaced farther from the edge of the shoe at the forepart than in the shank.

It has heretofore been proposed to provide common controlling means for the fastening inserting mechanism and the gage operable to shift the gage from one guiding position to another substantially simultaneously with the effect-nation of a change in the length of the nails inserted by the fastening inserting mechanism to facilitate the control of the machine by the operator by reducing the number of operations which it is necessary for him to perform in controlling the ma chine and to insure that the shifting of the edge gage Which might be neglected by the operator Will be effected at the proper time. Another object of the invention is to improve the character of such controlling means, the illustrated embodiment of the invention being characterized by the provision of poweroperated means for automaticallv controlling the fastening inserting mechanism and effecting movement of the gage. r

The construction and manner of operation of the fastening inserting instrumentalities and Work support of machines of the type disclosed in the above-mentioned patent is such that forward movement of the Work and consequently of the edge gage is per mitted during a small part only of the cycle of operations of the machine, namely, while the and is passing through the latter part of its feeding movement and is being Withdrawn from the Work. Accordingly, the operation of the edge gage moving means is so timed as to urge the gage forwardly during such part only of the cycle of operations. The arrangement of the and and edge gage relatively to each other and to the the work. Since the gage is moved one step only intermediate between the insertion of consecutively inserted fastenings, a number of fastenings are inserted between the rows of fastenings. Preferably, and as exemplified in the construction illustratedin Figs. 1 to 7 inclusive of the drawings, normally stationary operator controlled means is associated with the power-operated means for operative'ly connecting and disconnecting the power-operated means with and. from the gage;

Althoughthe inventionwill hereinafter be described as embodied in a machine for insertingloose nails, it is recognized that the u'se' of the invention'is not restricted thereto but that-"the invention as a whole and certain features thereof may have other applications including incorporation in other types of fastening insertingniachines. Moreover, the illustrated mechanism may be materially modified without departing from thescope of the-invention as defined in'the claims.

The machine in which the invention is li'erein'illustrated as embodied comprises a column 2 which supports the head 4: upon the front end of which are-mounted the fastening inserting instrumentalities comprising the a'wl6. A gage 8 is carried on the under side of the head adjacent to the point of insertion of the fastenings and acts to de termine the spacing of the fastenings from theedge of the work. I

' Means are provided for controlling the inserti'ng mechanism so as to causeit to insert selectivelynails of different lengths. In the illustrated construction, such means is generally of the type disclosed in the patent to Mackenzie 1,262,820, dated April 16, 1918, and for convenience in comparing the machine herein disclosed with that of said patent, similar reference numerals will be used to designate similar parts. The slide 280, upon which is mounted the actuator for shifting the raceway in the form of a double pawl 502, is reciprocated to bring said pawl into and outof engagement with one or the other of two shoulders 302 and 306 upon a horizontal slide 304 by connections with a bell crank lever 182, comprising a l'tll'k 2945 mounted upon said slide 280, and engaged by a segment rack 296 upon an arm 298 of the bell crank lever 182. The other arm of the lever .182 carries a cam roll which enters the cam groove 18-1 in the cam 48 upon the shaft 20 of the machine. The connections between the slide 301- and the double raceway 26% which has two slots designed to receive relatively long and short nails respectively comprise as shown in the patent t'o Goddu hereinafter mentioned, oppositely threaded rods 308 and 310 connected by an adjusting nut 312, the rod 308 being pivotally connected to the lug 314: upon the side of the double raceway. The rod 310 receives in an opening at one end an eccentric carried on the lower end of a rock shaft mounted'in a bearing in the bracket 272. said. rock shaft having formed upon its upper end a pinion 320 with which meshes a segment rack 322 formed on the end of the rock arm sea which i clamped upon the upper end of the rock shaft 326 also mounted in a bearing in the bracket 272 and carrying at its lower end a segment gear 328 which meshes with rack teeth 330 on the slide 301. teeth 330 are disposed at an inclination to the slide bar 30 1 and the bearings for the rockshaft 326 and 318 are correspondingly inclined thus serving to prevent binding when the inclined raceway is moved. The shifting movement of the slide 30 5; is sulli cient to turn the eccentric upon the shaft 318 around from one dead center to the other with respect to the rod 310 so that the raceway is positively shifted and positively held in either of its positions.

The pawl 502 i under the'control of a. pawl tipper 606 comprising arms 60S and 610 which carry respectively the do s 536 and 538. The pawl tipper 606 is formed with a hub mounted to turn freely on the shaft 614. The slide 280 is operated by power from the cam 41-8, being moved downwardly far enough for the pawl 502 to be ongaged and turned about its axis by the dog 53601 538 whenever the pawl tipper 606 has been set to effect shifting of the raceway. If the tipper is turned to the right to the position indicated in Fig. i, thc pawl 502 will be oscillated on its fulcrum 602 so as The rack i being crank 682. The

mally in short nail movement of the rod 692 weaves to cause its right hand end (Fig. 4) to engage the shoulder 302 of the slide 304 and thusshift the raceway in one direction. On the otherhand, movement of the pawl tipper 606 to the left effect engagement of the left hand end of. the pawl 502 with the shoulder 306 wherebythe raceway is moved in the opposite direction; The pawl tipper is norposition, 2'. 6., in position to cause the raceway to deliver short nails to the insertingmechanism, being yieldingly maintained in such position by a spring636 4) which is connected at one end to a screw or stud 638 upon the bracket 272 which carries the raceway shifting mechanism and at its other end is bent down so that it enters a socket 640 in the upper face of a bell crank lever 642 fulcrumed upon a stud 644 and having it its forward end a short rack 646 which engages teeth 648 in the periphery of the circular body portion of the tipper 606. Between the stud. 644 and the pawl tipper 606, the arm of the bell crank 642 is provided with an opening which receives a stud 650 servlng as a stop for the ver tical movements of the arm, the opening larger in diameter than the stud 650 whereby movement of the arm suflicient to reel: the pawl tipper between its two pawl tipping positions can take place.

. Preferably, for the purposes of this invention, the operation of the raceway shifting means is under the control of the operator. To this end, the bell crank lever 642 is formed with a second arm 676 havinga stop face 678 over which hooks a dog 680. guided upon a stud or screw 6558 received in a slot 686 of the dog for limiting its longitudinal movement and pivotally connected to an arm of another bell crank 682 fulcrumed at 684 upon a rearward extension of the bracket 272. A. second arm 690 of the bell. crank 682 is formed with a vertical here through which slides a rod 692 upon which is clamped acollar694 between which and the arm 690 of the bell crank lever is interposed a spring 606 through which force is transmitted from the rod 692 to the bell rod 692 is normally urged downwardly by a spring 698 acting against a part 700 fixed to the machine frame and a clamp collar 702 on the rod. Upward is effected by a treadle 704 and causes the pawl tipper 606 to be moved in opposition to the resistance of the spring 636 in a manner to initiate the movement of the raceway to a position to deliver a long nail. j

The edge gage and its adjusting means will now be described. As shown, the gage provided with a work engaging member 706 formed. to present a bearing surface 708 arranged to maintain guiding engagement with the work in any of its positions of adjustment. The member 706 is secured to in a channel formed in a block 714 secured to the head 4 of the machine by suitable means such as belts or the like. The gage is designed to be moved forwardly by the power of the machine and, to this end, the lateral extension 710 is preferably provided. with means adapted to be engaged by the power operated means. In the illustrated construction, the lateral extension 710 is formed on. its upper surface with teeth or corrugations 716 constructed for operation by a pawl 718 fulcrumed in an extension 720 of the lever722 by which the awl is forced downward to penetrate the work. The pawl 718 is engaged forwardly of its fulcrum 724 by a plunger 726 seated in a recess in the extension 720 and pressed against the pawl 718 by a spring 728 to maintain the active end of the pawl normally down in a position to engage the teeth 716 of the slide 712. The movement of the pawl under the impulse of the spring 728 is limited by a stop 730 disposed to engage its rear end. The range of movement of the pawl 71.8 by the lever 722 is such as to move the gage through a small distance only at each op eration, a number of operations of the pawl being required to accomplish the movement of the gage from its rearward to its forwardposition of adjustment. Inasmuch as the pawl is operated but once in each cycle of operations of the machine, it follows that in changing the insertion of the nails from one row to another, a number of nails will In order to preserve each of the accretions of movement of the gage in a forward direction and to retain the gage in its forward position of adjustment, the pawl 732 is pivoted on a stud 734 on the block 714 and is spring pressed downwardly into engagement with the teeth 736 on a second lateral extension 738 formed on the slide 712. The slide 712 is returned to its rearward position of adjustment by a spring 740 one end of which is received in a thimble 742 which is thereby pressed against a pin 744 depending from the slide 712 into a slot 746 in the block 714. A set screw 748 is projected into the end of the slot opposite the thimble 742 and constitutes an adjustable stop for limiting the movement of the gage by the spring 740.

j The operating means for the edge gage is controlled by the operator by means com prising a double cam member 750 slidably mounted-on the block 714 and having afor- V ward cam section 752 operable to elevate thus permitting the pawl shifter 606 to be.

the active end of the pawl 718 from the teeth 716 and toretain the pawl in such position to preclude movement of the slide thereby and a second cam section 754; for raising the pawl 732 from engagement with the teeth 7 86 on the lateral extension 7 38 to permit the gage to be moved backwardly by the spring 740. The member 750 is nor mally urged r arwardly by a spring 7 received in a thimble 7 56 engaging the depending end 757 of said member and is provided with a recess 758 which receives a stud 759 on an arm 7 (30 mounted on a shaft 762' journaled in the block 7% and having at its other end an arm 763 connected by a link 764 to the arm 766 formed with the bell crank lever 682 so that upon actuation of the rod 692 by the treadle 704, the operation of the raceway shifting mechanism'and the ga e moving means may be simultaneously. initiated.

The manner of operation of the invention will be described with particular reference to Fig. 1O which shows a shoe comprising an upper A, outsole B, and slipsole C. The shoe is presented to the machine in the usual manner, 2'. 6., with the toe at the right of the point of insertion of the nails. The gage being in its forward position of adjustment and the raceway being in a position to deliver short nails, a row of such nails indicated by the bracket D is inserted in the shank of the shoe close to its edge. 'lVhen the fore part is reached, however, the operator depresses the treadle st and thereby moves the pawl shifter so thatupon the next operation of the slide 280, the raceway 264: is shifted to a position to deliver long nails as required by the greater thickness of the material in the forepart. The depression of the treadle also through its connections with the arm 760 moves the cam member 750 forwardly thus elevating the pawls 718 and 732 from the gage slide 712, whereupon the gage is moved to its rearward position of adjustment by the spring 74:0, which is also its retracted gaging position. Upon continued operation of the machine, therefore, .a row of long nails is inserted about the forepart at a distance more remote from the edge of the shoe than in the shank which as hereinbefore pointed out is desirable because of the greater projection "of the sole 1n the forepart.

lVhen the shank of the shoe is reached on the other side, the operator removes his foot from the treadle moved to short nail position by the spring 686 and the cam member 750 to be thrust back by the spring 7 55 to effect engagement of the pawls 718 and 782 with the gage. The lever 722 is operated to begin the withdrawal of'the awl from the work before the "feeding movement of the awl is completed.

Consequently, inasmuch as the pawl 718 is actuated in a direction to move the gage forwardly when the lever 722 raises the awl, forward movement of the gage will be effected during the latter part of the feeding movcment of the awl and while the awl is in the work. The machine is thus caused to insert short nails at the proper decreased distance fromthe edge of the shoe. The nails, which as above mentioned are inserted in the shoe intermediate between the rows, are designated in Fig. 10 by the reference characters E. and F respectively, and the row of short nails in the shank is marked out by the bracket H. From the foregoing, it will be understood that the operation of the machine on a piece of work is completed with the gage in forward position, that is, with the gage in advanced gaging position, and that the gage will be in such position when a fresh piece of work is presented to the machine.

In the employment of fastening inserting machines on many kinds of work, for example, in the manufacture of shoes of certain styles, it is necessary to move or adjust the gage during the operation of the machine on a single piece of work. The adjustment of the ed e gage is effected without checking the operation of the machine, and has heretofore, so far as applicant is aware, been manually performed. Inasmuch as the machine operates very rapidly and the edge gage is capable of adjustment in the direction of the work during the small part only of the cycle of operations of the machine in which the awl is passing through the latter part of its feeding movement and is being withdrawn from the work, the work and, consequently, the gage being withheld from movement at other times by reason of being clamped between the work support and foot plate of the machine or by reason of the pro jcction of the awl into the path of movement of the gage, the operator must act very quickly to effect complete adjustment of the gage at the desired point of the work. Consequently, in prior constructions, it results frequently that the operator effects only an incomplete adjustment of the gage in the short space of time permitted for the opera tion, thus causing uneven work. The provision, in the illustrative machine, of power operated means for effecting the movements of the gage, it being understood that the gage is moved rcarwardly by power stored in the spring on its forward movement, insures prompt movement to the full limit of its adjustment in either direction.

The embodiment of the invention illustrated in Figs. 8 and 9 is applied to a machine in which the raceway is automatically shifted by mechanism of the type shown in the patent to Goddu above mentioned. Many of the elements of such mechanism are identical with parts of the raceway shifting means tending to move the gage rearwardly. A;

hereinbefore set forth, and since it is believed that a further reference to such parts 1s unnecessary to a complete disclosure'of the in vention, the mechanism. will be described only in the respects in which it differs from such construction. In the operation of machines of the type disclosed in the Goddu patent, the work is mounted on a horn 780 i by which it is held against the foot plate of the machine. The horn and foot plate serve to caliper the work and inasmuch as the foot plate is lined in its position, the horn will be elevated to an extent depending upon the thickness of the work at the point engaged by it. The double pawl 502 is automatically shifted by a pawl shifter 782 controlled'by' connections withthe horn 780 so that the raceway 264 is shifted to deliver a long nail or a short nail accordingto the thickness of the work indicated by the horn. The pawl shifter 7 82 is mountedon a shaft 784 having at one end a pinion 786 meshing with teeth on a segment arm 788 eatendlng from a shaft 790 upon which is mounteda lever 792 connected by a link794c with a lever 796 ful- 1 crumed on the machine frame and connected to the horn 780 at T 98.

Slidablymounthd ona bracket 800 carried by the machineframe is a gage member 802 *niatically moved from one gaging position to another, the slide barBOt is extended beyond the rack 330 as indicated at 809 and 40 to the upper end of a lever 81a fulcrumed at 816 to an upwardly eirtending portion 818 having a spring 804: connected thereto and sctscrew 806 disposed to engage a pin 808 depending from the gage slide adjustably' limits the movement of the gage in such direction. i

To the end that the; gage may be autohassecured in its end a stud 810 grooved to receive the hooked end "of a link 812 joined of the bracket 800. The lever "81 i is provided at its lower end with teeth meshing witha pinion820 on a shaft 822 journaled inthe bracket 80 0and formed with an cecentric portion 82t engaging a lug 826 on the gage 1 slide and [operable upon angular movement of the shaft 822 to move the gage forwardly in opposition to the spring 804.

A. spring 828 connected at one end to a pin 880 on the link 812 and at its other end to j sired. The arrangement of the above-described parts is'such that when the bar 304: moved in a direction to shift the raceway to short nail position, the extension 809 of the pin. 832 retains the link 812 in engagement withthe stud 810 but permits it to be readily detached from the stud when dethe bar through its connections with the gage moves it forwardly against the resistance of the spring 804.
